Is this a warning signal to inerrantists?

The fundamental problem with books like this is that they fly in the face of what seems obvious to everyone else who doesn’t already hold the a priori belief that everything the Bible says must be true, just because the Bible says it. To paraphrase something Nick Trakakis wrote in another context, “Defenses of genocidal behavior by the OT god turn a blind eye to what seem clear and obvious to everyone else — that such behavior makes a mockery out of what any person would consider morally justifiable behavior.”[1]

i) I'm happy to concede that we defend things we think are true which we wouldn't defend if we didn't think they were true. I don't regard that as a damning admission.

ii) Since Bible writers clearly viewed this behavior as morally justifiable, to say it "makes a mockery out of what any person would consider morally justifiable behavior" preemptively excludes anyone who disagrees with Jeff. Nice circular logic. "Obvious to everyone else" is code language for "anyone who happens to share Jeff's sentiments." 

iii) As I've explained elsewhere, the commands aren't "genocidal." Jeff is simply parroting what others say rather than thinking for himself.

iv) Then there's the standing irony of atheists who ride around on their moral high horse. But Jeff doesn't attempt to show how atheism can justify moral realism. 

And even if atheism could justify moral realism, that falls went short of showing how ephemeral, fortuitous organizations of matter (i.e. humans) have rights.
